Question
- A. In the car braking scenario, apply acceleration to describe how to investigate the effect of changing mass on the acceleration of a trolley while keeping mass versus weight separate.
- B. In the car braking scenario, mix up mass versus weight and ignore acceleration.
- C. Use a general revision statement without applying Required practical: acceleration to the situation.
- D. Choose a different forces topic instead of explaining describe how to investigate the effect of changing mass on the acceleration of a trolley.
Answer
The correct answer is: In the car braking scenario, apply acceleration to describe how to investigate the effect of changing mass on the acceleration of a trolley while keeping mass versus weight separate.
Explanation
The correct option is In the car braking scenario, apply acceleration to describe how to investigate the effect of changing mass on the acceleration of a trolley while keeping mass versus weight separate.. It is correct because the scenario says a car driver reacts, brakes, and transfers kinetic energy thermally, which must be interpreted through Required practical: acceleration. This directly supports the learning objective to describe how to investigate the effect of changing mass on the acceleration of a trolley. Use values 4, 15, and 17 only if the question asks for a calculation. The answer earns credit by naming the relevant force or motion quantity, using units when needed, and avoiding the boundary error mass versus weight.
Common mistake
Confusing Mass and Weight
Students often confuse mass with weight, thinking they are the same. They may state that mass is measured in newtons instead of kilograms.
Remember that mass is a measure of the amount of matter in an object and is measured in kilograms (kg), while weight is the force acting on that mass due to gravity and is measured in newtons (N).
